Abstract
The utility model relates to a corrugated expansion joint with an alarm device. The corrugated expansion joint comprises a joint pipe, a flange, a double-layer corrugated pipe and a flow guide pipe; a left joint pipe and a right joint pipe are arranged at two ends of the corrugated pipe respectively; the outer sides of the left joint pipe and the right joint pipe are connected with a left flange and a right flange respectively; the left flange is connected with the right flange through a pull rod and a nut; one end of the flow guide pipe is fixedly connected with the inner surface of the left joint pipe; the other end of the flow guide pipe extends into the right joint pipe; the connection position of the double-layer corrugated pipe and the joint pipe is provided with a communication pipe; the communication pipe is communicated with an empty chamber which is formed by a middle interlayer of the double-layer corrugated pipe; the end portion of the communication pipe is provided with the alarm device which comprises a gas, temperature and pressure sensor. According to the corrugated expansion joint with the alarm device, the end portion of the communication pipe is provided with the alarm device and accordingly a leak point can be found and an alarm signal can be sent out timely through the alarm device once leakage of an inner layer of the double-layer corrugated pipe of the expansion joint is produced and the expansion joint can be rapidly maintained or replaced conveniently. The corrugated expansion joint with the alarm device is suitable for conveying of a pipe which is inflammable and explosive or comprises the corrosive fluid and accordingly the safety of the pipe is ensured and the normal running of the pipe is guaranteed.
Description
Technical field
The utility model relates to pipeline extension expansion compensation device, especially a kind of corrugated expansion joint with warning device.
Background technique
At present, it is some for compensating the expansion joint of pipeline extension that existing heat supply pipeline all needs segmentation to install, and especially for carrying the length of high temperature, high-pressure medium apart from heat supply pipeline, the wall thickness of expansion joint is large, intensity is higher.In using process, the extending amount producing due to heat supply pipeline is larger, and bellows wave number is more, and the bellows of expansion joint is easily because local leakage appears in fatigue.Therefore need to find in time leakage failure and determine leakage point, so that rapid-maintenance or replacing expansion joint ensure the normal operation of pipeline.
Model utility content
The purpose of this utility model is to provide one can find the concurrent alarm signal of sending of leakage point in time, with the corrugated expansion joint of warning device.
The purpose of this utility model is achieved by the following technical solution:
With the corrugated expansion joint of warning device, comprise adapter, flange, bellows and honeycomb duct, the two ends of described bellows are respectively equipped with left adapter and right adapter, the outside of left adapter and right adapter is connected respectively left flange and right flange, between left flange and right flange, be connected with nut by pull bar, one end of described honeycomb duct is connected and fixes with the internal surface of left adapter, the other end of honeycomb duct extend in the inner chamber of right adapter, described bellows is double-ply bellows, the link position of double-ply bellows and left adapter or right adapter is provided with connecting tube, this connecting tube is connected with the cavity that double-ply bellows intermediate course forms, the end of described connecting tube is provided with warning device, described warning device comprises gas, temperature and pressure sensor.
As optimal technical scheme of the present utility model, described warning device is connected with controller by signal transmitting apparatus.
As optimal technical scheme of the present utility model, described warning device is connected with central control room by signal transmitting apparatus.
As optimal technical scheme of the present utility model, described signal transmitting apparatus comprises wireless signal transmitting device or wire signal transmitting set.
As optimal technical scheme of the present utility model, described left flange and right flange are respectively equipped with otic placode, between left flange and the otic placode of right flange, are connected with pull bar and nut.
As optimal technical scheme of the present utility model, described connecting tube is also provided with valve near the position of warning device.
The beneficial effects of the utility model are: with respect to prior art, the end of the utility model connecting tube is provided with warning device, once the internal layer of expansion joint double-ply bellows leaks, warning device can be found in time leakage point and send alarm signal, so that rapid-maintenance or replacing expansion joint.The utility model is applicable to carry inflammable, explosive or has the pipeline of corrosive fluid, thereby guarantees pipe safety, ensures the normal operation of pipeline.
Brief description of the drawings
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local enlarged diagram of I portion in Fig. 1.
